NASA-STD-5019A, NASA TECHNICAL SPECIFICATION: FRACTURE CONTROL REQUIREMENTS FOR SPACEFLIGHT HARDWARE (01-FEB-2016)
NASA-STD-5019A, NASA TECHNICAL SPECIFICATION: FRACTURE CONTROL REQUIREMENTS FOR SPACEFLIGHT HARDWARE (01-FEB-2016)., The purpose of this NASA Technical Standard is to establish the fracture control requirements
for National Aeronautics and Space Administration (NASA) human-rated spaceflight hardware.
In accordance with NASA Procedural Requirements (NPR) 8705.2B, Human-Rating
Requirements for Space Systems, it is NASA’s policy to produce human-rated space systems
that have failure tolerance for catastrophic events or that potentially catastrophic hazards are
controlled through a defined process in which approved standards and margins are implemented
that account for the absence of failure tolerance.
This NASA Technical Standard supersedes the baseline release of NASA-STD-5019, Fracture
Control Requirements for Spaceflight Hardware.
Programs that are not human-rated may choose to impose these requirements on a mission or
hardware to bolster the program or to serve as a stepping-stone for human rating. This NASA Technical Standard is published by the National Aeronautics and Space
Administration (NASA) to provide uniform engineering and technical requirements for
processes, procedures, practices, and methods that have been endorsed as standard for NASA
programs and projects, including requirements for selection, application, and design criteria of an
This NASA Technical Standard is approved for use by NASA Headquarters and NASA Centers
and Facilities and may be cited in contract, program, and other Agency documents as a technical
requirement. It may also apply to the Jet Propulsion Laboratory and other contractors only to the
extent specified or referenced in applicable contracts.
This NASA Technical Standard establishes the fracture control requirements for human-rated
spaceflight, since NASA policy states that fracture control be imposed on all human-rated
spaceflight hardware. It was developed by a NASA-wide Fracture Control Working Group to
provide a common framework for fracture control practices on NASA programs.
